During Arctic springtime, halogen radicals oxidize atmospheric elemental mercury (Hg0),
which deposits to the cryosphere. This is followed by a summertime atmospheric Hg0 peak …

The Arctic plays a critical role in the global Hg cycle as both a sink of Hg and, in response to
rapid global warming, an emerging source of Hg due to release from permafrost and …

Anthropogenic mercury (Hg) emissions have driven marked increases in Arctic Hg levels,
which are now being impacted by regional warming, with uncertain ecological …

The tundra plays a pivotal role in the Arctic mercury (Hg) cycle by storing atmospheric Hg
deposition and shuttling it to the Arctic Ocean. A recent study revealed that 70% of the …

Anthropogenic activities have led to large-scale mercury (Hg) pollution in the Arctic,,,,,. It has
been suggested that sea-salt-induced chemical cycling of Hg (through 'atmospheric mercury …

Atmospheric gaseous elemental mercury (GEM) concentrations in the Arctic exhibit a clear
summertime maximum, while the origin of this peak is still a matter of debate in the …

Clarifying the sources and fates of atmospheric mercury (Hg) in the Antarctic is crucial to
understand the global Hg circulation and its impacts on the fragile ecosystem of the …

Springtime atmospheric mercury depletion events (AMDEs) lead to snow with elevated
mercury concentrations (> 200 ng Hg/L) in the Arctic and Antarctic. During AMDEs gaseous …

Dramatic environmental shifts are occuring throughout the Arctic from climate change, with
consequences for the cycling of mercury (Hg). This review summarizes the latest science on …

Gaseous elemental mercury (Hg0) is a globally distributed air toxin with a long atmospheric
residence time. Any process that reduces its atmospheric lifetime increases its potential …
